Discrete Hilbert Transform

2017
Having introduced circle packings and all technical auxiliary material, we are now in a position to address boundary value problems for circle packings. Throughout this chapter, K will continue to be a fixed complex for which we retain the same notation as previously.

Hilbert-Transformation (HT)

1985
In Aufgabe A7.1 wird die HT im Zeitbereich angewendet, auserdem wird der „Hilbert-Transformator“ eingefuhrt, dessen Impuls- und Sprungantwort in weiteren Aufgaben dieses Kapitels Anwendung findet. Die HT im Frequenzbereich verbindet Real- und Imaginarteil der Ubertragungsfunktion eines realisierbaren Systems. Dies wird in 7.2 naher untersucht.
